Curry bought one of two winning tickets for the drawing Tuesday night. The other was sold in California, but the winner did not immediately come forward.

Georgia lottery officials said that Curry bought only the one ticket, a last-minute decision, and played a combination of family birthdays and her family’s lucky number, seven — the critical Mega Ball in the drawing Tuesday night.

“She was just in a state of disbelief,” said Debbie Alford, the Georgia lottery president.

Curry selected a single-payment option, rather than an annuity, and will take home about $120 million after federal and state taxes, the officials said.

Curry, who lottery officials said was driving when she heard about the winning numbers, did not appear at a Georgia lottery press conference. Lottery officials said they had spent a couple of hours with her and her husband, and that “she’s gonna take some time and think about it.”

Curry's employer congratulated her in a statement released Wednesday: "Aspen Insurance congratulates Ira Curry, a vice president based in Atlanta, on winning yesterday's Mega Millions jackpot. Ira is a valued long-term employee with Aspen, and the entire Aspen team is thrilled for her and her family. It could not have happened to a nicer person, and we are excited for her good fortune."

The winning tickets were sold at an office-building newsstand in Atlanta and at a shop in San Jose, Calif. And fortunes were very different for the two sellers. Because of differing lottery rules in their two states, one gets $1 million, while the other has to settle for publicity.

For selling a lucky ticket at his store, Jenny’s Gift & Kids Wear in San Jose, owner Thuy Nguyen will get a $1 million bonus. California lottery rules provide a retailer bonus of 0.5 percent of the prize, up to $1 million, a spokesman said.

Nguyen was called by state lottery officials Tuesday and rushed to his store. He said that he was so excited he wouldn’t be able to sleep.

Asked what he planned to do with the money, he said: “For my family, a house. And try to invest.”

It was a different story in Atlanta. Georgia lottery rules provide no retailer payout, spokeswoman Tandi Reddick said. Retailers get a flat 6 percent commission on the sales of the $1 tickets themselves, but no bonus for a winning ticket, she said.

Georgia retailers that have sold winning tickets in the past have also received giant fake checks to display.

“Of course, this location now has the distinction of being known as a lucky store, which is exciting news for them,” Reddick told NBC News in an email.

The owner of the Atlanta newsstand, which is in the upscale Buckhead neighborhood, is Young Soo Lee, 58, a Korean immigrant who said that she came to the United States in 1980.

There was some confusion at the Atlanta store after word arrived that one of the winning tickets was sold there. A CNN crew informed the store owner that she, too, was getting a $1 million bonus.

“Oh, my gosh!” she said, clutching her heart.

She told NBC News later that she was “a little mad” that she wasn’t getting the retailer bonus, but still excited that her store won.

In years past, according to news accounts, Georgia stores that have sold winning Mega Millions tickets have received a $25,000 bonus. Reddick, the spokeswoman, did not immediately respond to a question about when the bonus was phased out.

The winners beat odds of about 259 million to 1. The jackpot was the second-largest in American history, trailing only a $656 million draw last year, and could have approached $1 billion if no one had won.

In Nipton, Calif., so many people lined up to buy a ticket that the line stretched into the next state over, Nevada — because it’s one of seven states that don’t offer Mega Millions.

The surge of spending pushed the prize closer to the record U.S. jackpot of $656 million, won in March 2012 in a Mega Millions drawing.
